In 2006, the Signal Processing Department at Blekinge Institute of Technology and Axiom EduTECH in Sweden worked with National Instruments Corporation in Texas, USA, to set up the Virtual Instrument Systems in Reality (VISIR) Project, which operates as a remote laboratory for electric and electronic circuits.The VISIR remote laboratory is currently the only system that delivers practical experiments with electronics without the need to go to a traditional lab. This is of increasing importance given the expansion of online education. There is a mass of scientific literature that collects results on the use of VISIR remote laboratory, however, there are few reference works that provide an in-depth exploration of the laboratory's performance and potential. VISIR Handbook acts as a guide for users, demonstrating many of the real (remote) experiments that can be achieved and replicated with this laboratory. Most importantly, this book demonstrates how VISIR can be used as a learning tool for students. The approach of the book is designed on two levels, with an administratorresearcher approach and a teacherstudent approach. VISIR offers users full control of the experiment since they can change both the logic structure of the experiment (build the circuit they want) and the excitation values of the input signals. Similarly, a user can configure the measuring instruments on a variety of scales, making it ­possible to analyze the behavior of the circuit under test from different perspectives.
